Adjusting The Carburetors; Adjusting The Engine Idling Speed - Yamaha FZS1000 Owner's Manual

Adjusting the carburetors

The carburetors are important parts of
the engine and require very sophisticat-
ed adjustment. Therefore, most carbu-
retor adjustments should be left to a
Yamaha dealer, who has the neces-
sary professional knowledge and expe-
rience. The adjustment described in the
following section, however, may be ser-
viced by the owner as part of routine
maintenance.
CAUTION:
The carburetors have been set and
extensively tested at the Yamaha
factory. Changing these settings
without sufficient technical knowl-
edge may result in poor perfor-
mance of or damage to the engine.
